sists in the novel construction and arrangement of its parts ashereinafter shown and described.

The object of the invention is to provide a machine of the characterindicated which in turn is provided with a series of rotating pickers.Means is provided for reciprocating the said pickers longitudinally asthey rotate and means is also provided for moving the pickers in anorbit during their reciprocation.

The machine is adapted to travel or move over the surface of the groundwhile in operation and consequently the pickers in addition todescribing an orbit which is of sinusoidal configuration the saidpickers at the same time progress or move with the machine. A rotatingbrush is carried by the machine and has engagement with the pickers andthe said pickers move transversely in relation to the brush while thebrush rotates in an opposite direction to that which the pickers move indescribing their orbit. The means for causing the pickers to movelongitudinally or reciprocate consists of a cylinder having at itsperiphery an annular groove spirally disposed. A block is carried byeach picker and each block is provided with a laterally disposed lugwhich is located in the said groove of the disk. The

said pickers are journaled for rotation in the said block but movelongitudinally with the same consequently when the said disk rotates theblocks are raised and lowered and reciprocatory movement is transmittedto the pickers. An engine or other suitable means is provided foractuating the movable parts of the machine. A series of hinged sectionsis provided in the bottom of the machine and an endless belt conveyor ismounted upon each of the said hinged sections. Each section is providedwith a runner or its equivalent which is adapted to have contact withthe ground and consequently the said sections are swung upon theirhinges as the 5 said runner moves over the uneven surfaces of theground. The endless belts or conveyers carried by the sections arelocated in advance of the transversely disposed belts or conveyors and abrush or its equivalent is carried by each hinged section and isjournaled for rotation and is adapted to cast the cotton bolls or lintupon the said endless conveyer. A suction fan is located at the rear endof the machine and a pipe from the inlet of the fan casing terminatesover the outer end of the said transversely disposed conveyors or beltsand the cotton which is deposited upon the said transversely disposedbelts is sucked up through the said inlet pipe into the casing and thestaple is then forced through other pipes into a cleaner. From thecleaner the staple is lead through the discharge pipe into a chuteprovided for its reception and from the same the staple is permitted tofall into bags or other receptacles.

The machine consists of the platform 1 the forward end of which ismounted upon the dirigible wheel or wheels 2. The rear portion of theplatform is supported by the ground wheels 3. The body or casing 1 ismounted upon the platform 1 and the said platform is provided with anopening for the reception of the said body or casing. Thesuper-structure 5 is mounted upon the upper end of the said body orcasing 4, and consists of the radially disposed arms 6 which areprovided at their outer ends with the yokes 7 which in turn merge withor are located upon the upper end portions of the said body or casing 4.The bearing 8 is mounted upon the arms 6 and is provided with a ballrace 9 which receives anti-friction bearing balls 10. The cap 11 isattached to the vertically disposed shaft 12 which is journaled forrotation in the bearing 8. The said cap is provided with the ball race13 which also receives the said balls 10. The disk 14 surrounds theshaft 12 and is adapted to rotate with the same but may have limitedlongitudinal movement along the said shaft. The said disk 14 is providedat its middle with a cavity 15 which receives the coil spring 16. Thesleeve 17 is screwthreaded in a recess provided in the under side of thearms 6 at the point where the shaft 12 passes through the same and thelower end of the sleeve 17 presses upon the upper end of the spring 15.It is obvious that by turning the sleeve 17 that the tension of thespring 15 may be increased or diminished. The frame 18 is provided atits upper end with the parallel spaced disks 19 and 20 and at its lowerend with the disk 21. The said disks 19, 20 and 21 are loosely journaledupon the shaft 12. The disk 19 is provided upon its upper surface with aconcentric set of gear teeth 22. The horizontally disposed shafts 23 arejournaled for rotation in the superstructure 5 of the machine and thesaid shafts are provided at their outer ends with the pinions 24 whichare in mesh with the gear teeth 22 upon the upper disk 19 of the saidframe 18. Means is provided for rotating the frame 18 as will behereinafter explained. The hubs 25 and 26 are fixed upon the shaft 12and are provided with spokes 27 which connect with the cylindrical rim28. The said cylinder is provided at its periphery with an annularinclined groove 29. The machine is provided with a series of pickers 30.Each picker consists of a shaft 31 the upper end portion of which passesthrough registering perforations in the disks 19 and 20 and the lowerend portion of which passes through the perforation 31 provided in thedisk 21. The lower end portion of each picker is provided with bristlesor brushes 32 and the upper end portion of each shaft 31 is slidablymounted between the disks 19 and 20 and is held against lateral movementby the said disks. The said shafts 31 are feathered in the pulleys 33and consequently they rotate with the said pulleys but may movelongitudinally through the same as above stated. The collars 34 arefixed to the shafts 31 of the said pickers and ablock 35 is locatedbetween each pair of collars 34 and is loosely journaled upon the shaftof the plcker 30. Each block is provided with a laterally disposed lug36 and the said lugs of all the blocks enter the annluar groove 29 ofthe cylinder 28. The lower end of the shafts 31 are pointed as at 37.The brush 38 is fixed to the lower end of the shaft 12 and is locatedbelow the disk 21 of the frame 18. The said brush is provided at itsperiphery with the bristles 39 which have contact with he bristles 32 ofthe picker 30. The friction pulleys40 are mounted upon the shafts 23 andare located over the upper side of the super-structure 5. The peripheralportion of the disk 14 rests upon the upper sides of the said frictionpulleys 40 and the said disk 14 is held in frictional contact with thesaid pulleys 40 under the tension of the spring 15.

The sides 41 depend from the platform 1. A shaft 42 is journaled forrotation at the lower end of side 41 in suitable brackets 42 and eachshaft 42 is provided with a friction disk 43. The arms 44 are pivotallymounted upon the shaft 42 and the shaft 45 is journaled for rotation atthe inner ends of the arms 44. A belt pulley 46 is mounted upon theshaft 42 and the belt pulley 47 is mounted upon the shaft 45. Theendless belt 48 passes around the pulleys 46 and 47 The guide 49 islocated at the forward end of the shaft 45. The brush 50 is mounted uponthe shaft 45. The shafts of the rolls 51 and 52 are journaled in thelaterally extending lugs 44, carried by the arms 44. The endless belt 53passes around the rolls 51 and 52. The friction wheel 54 is mounted uponthe shaft of the roll 52 and has frictional contact with the disk 43mounted upon the shaft 42. The grating 55 is lo cated over the endlessbelt 53 and is provided with the curved end portions 56' which arelocated over the brush 50. The said grating 55 is supported by the beam56 which in turn is supported by the arms 44. The flooring 59 isattached at one edge to the beam 56 and is provided at its oppositelongitudinal edge with a depending runner 60. The said runner 60 isadapted to pass along the surface of the soil and serves as a guide tohold the endless belt 53 and the conveyer belt 48 at a uniform heightabove the surface of the ground.

The engine 61 is mounted upon the forward end portion of the platform 1and the belt pulley 62 is mounted upon the shaft 63 of the said engine.The shaft 64 is journaled for rotation in the brackets 65 which in turnare mounted upon the forward portion of the body 4 and the belt pulley66 is mounted upon the said shaft 64. The belt 67 passes around thepulleys 62 and 66 and is adapted to transmit rotary movement from theengine shaft 63 to the shaft 64. The friction disk 68 is mounted uponthe shaft 64 and the vertical shaft 69 is journaled for rotation in thesaid bracket 65.

The disk 70 is mounted upon the shaft 69 riphery of the disk 68.

and normally bears against the upper portion of the periphery of thefriction disk 68. The said disk 70 is held in frictional contact withthe disk 68 by means of the coil springs 71 which bears at its lower endagainst the upper side of the said disk 70 and at its upper end againstthe under portion of the upper sides of the bracket 65. The tension ofthe said spring 71 is governed by the nut 72 which is screw threaded ina perforation in the upper portion of the bracket 65 and which bearsagainst the upper end of the said spring 71. The lever 73 is fulcrumedupon the bracket 65 and is connected at its lower end portion with theshaft 74. The eccentric 75 is mounted upon the shaft and is adapted tohave contact with the under side of the disk 70 when the lever 73 isswung the said eccentric 75 is adapted to lift the disk out of contactwith the pe- The periphery of the disk 70 engages the upper portion ofthe frame 18 frictionally, or by coggear, as desired and it is obviousthat as the said disk 70 rotates, rotary movement is transmitted fromthe same to the said frame 18. The disk 20 is loosely mounted upon theshaft 12 and the pulleys are slidably mounted upon the shafts 31 of thepickers. By reference to Fig. 9 of the drawing it will be seen that anendless belt 76 passes around the disk 20 and also has contact with thesides of the pulleys 33. The tension device 77 is mounted upon the disk20 and engages the endless belt 76 and is adapted to keep the same taut.The belt has contact with the opposite sides of the adjacent pulleys 33so that the said pulleys rotate in opposite directions with relation tothe pulleys next adjacent. Therefore it will be seen that the shafts 31alternately rotate in opposite directions and the pickers 80 rotateaccordingly.

The worm gears 78 are mounted upon the end portions of the shaft 64 andmesh with the pinions 79 mounted upon the vertically disposed shafts 80.The beveled pinions 82 are carried by the lower ends of the shafts 80and mesh with the beveled pinions 83 located upon the shafts 42. Thefans or blowers 81 are located at the rear end portion of the frame 1and the shaft 82 of each said fan or blower is provided with a pulley83'. The endless belt 84: passes around the pulleys 83 and the pulley 84located upon the shaft 64. The upper end of the pipe 85 connects withthe inlet end of the casing of the fan 81 and the lower end of the saidpipe 85 is disposed above the outer end portion of the endless conveyer48. The lower end of the discharge pipe 86 connects with the fan casing81 and at its upper end the said pipe 86 connects with the cylinder 87.The concaved screen 88 is mounted in the interior of the cylinder 87 andthe foraminous drum 89 is journaled for rotation in the said cylinder87. The said drum is provided upon its periphery with a series ofradially disposed pins 90. The cylinder 87 is provided with an outletopening 91 which communicates with the chutes 92. The chutes 92 are induplicate with their upper ends verging into or connecting directly withthe discharge outlet 91 of the cylinder 87. The valve 93 is mountedwithin the chutes 92 and may be disposed or swung to one side or theother for the purpose of directing the material which is delivered fromthe cylinder 87 into either one or the other of the chutes 92 asdesired. The bags or receptacles 94L are adapted to be located upon therear end portion of the platform 1 and are connected at their upper endswith the lower ends of the chutes 92 and may receive cotton from eitherone of the said chutes.

The shaft 95 is journalcd for rotation at the upper rear end portion ofthe frame 5 and the belt pulleys 96 are mounted upon the end portions ofthe said shaft 95. The pulleys 97 are mounted upon the shaft 64L- andthe endless belts 98 pass around the pulleys 96 and 97. The pulley 99 ismounted upon the shaft of the drum 89 and the pulley 100 mounted uponthe shaft 95. The endless belt 101 passes around the pulleys 99 and 100and isadapted to transmit rotary movement from the shaft 95 to the drum89.

The operation of the machine is as follows. As the machine is movedalong the surface of the ground and longitudinally along a row ofstanding plants the guides 49 direct the lower portions of the stalks ofthe plants between the brushes 50 or their equivalents at the same timethe frame 18 is rotated as above described while the shaft 12 is rotatedin the opposite direction. As the said frame 18 rotates it carriesaround with it the pickers 30 in an orbit and as the cylinder 28carrying the groove 29 is turning in the opposite direction and the saidgroove 29 is inclined and in contact with the lugs 36 of the blocks 35the pickers 30 are moved in a sinusoidal orbit, that is to say they arereciprocated longitudinally with relation to the brush 38 while theymove in the path of a circle. As the said pickers 30 reciprocatelongitudinally they come in contact with the cotton borne upon thebranches of the plants and force the same down upon the endlessconveyors 53. The brush 38 removes the lint from the bristles 82 shouldany cling thereto and the said lint thus removed from the said bristles32 falls upon the endless belt conveyors 53. The grate 55 preventssticks and other trash from falling upon the said endless conveyors Asthe said conveyers 58 are in motion as above described the staple iscarried back toward the transversely disposed conveyers 48 and isdeposited upon them. As the said conveyers 48 are moving at their uppersides toward the lower ends of the pipes 85 the staple is carried underthe ends of the said pipes and is drawn up through the pipes in responseto suction created by the fans 81. From the fans 81 the staple is forcedup through the discharge pipe 86 into the cylinder 87. \Vhen thematerial enters the cylinder 87 it is caught up by the pins 90 andcarried around the concave 88 and the sand and grit are separated fromthe cotton and passed through the said concave. The grit and othermatter thus separated passes down through the pipes 102 from whence itis discharged. The cotton that adheres to the pins 90 is carried arounduntil it reaches the outlet 91 of the cylinder 87 and it then passesthrough the said outlet into the chutes 92. From this point the cottonfalls upon the valve 93 and is deflected into a bag or other receptacle94. It will be observed that the blasts of air which are created by thesuction fans 81 operate on the material while it is in the cylinder 87and the air may have a comparatively unobstructed passage through thedrum 89 while the cotton and other materials are carried around with thesame. Consequently as the air emerges from the interior of the drum 89in an effort to make its escape through the outlet 91 it will force thematerial from the pins 90 and from the periphery of the drum 89.

The machine as hereinbefore described, includes the principal parts ofthe invention and the general arrangements thereof. Variations may bemade in such arrange ments as will be hereinafter explained and whichare illustrated in several of the views of the drawings. For instance,as illustrated in Fig. 10 of the drawings, the lower portions 30 of thepickers may be separated or detached from the picker shafts 31,consequently, when the bristles upon the said portions 30 become wornthe said portion may be removed and a portion having new bristles may besubstituted in its stead. As illustrated in the said figure, thebristles 32 are spirally mounted upon the pickers and may be of steel,hair, bristle, or other suitable material, but preferably of ordinarybristle. As above described, the bristles on the adjacent pickers movetoward each other and as they are spirally disposed as shown, with thespirals upon one member of the pair of bristles oppositely disposed tothe spiral upon the other member, this disposition of the bristlesfacilitates the removal of the cotton from the plants. When the cottonis engaged by the said bristles it is driven down toward the beltconveyers 53 and is at the samev time given a twist by the saidbristles, which has a tendency to tear the cotton from the boll and alsoto deposit the same upon the said belt conveyers.

Should any of the cotton lint adhere to the bristles of the pickers itwill be operated upon as the said picker ascends by the brush 38. Thesaid brush 38 may have bristles 39 as illustrated in Fig. 2 of thedrawings, or it may be provided in lieu of the said bristles withfan-shaped blades which will have a tendency to blow the lint from thebristles of the pickers and cast the same down upon the endless conveyerbelt 53.

As illustrated in'Fig. 12 of the drawings the blocks 35 may be providedwith the friction rollers 36 mounted upon the lugs 36. The said rollers36 will travel in the spiral groove 29 provided in the periphery of thecylinder 28 and will reduce the friction be-' tween the said blocks andthe said cylinder. It will also be seen by reference to Fig. 2 of thedrawing that the frame 18 is mounted upon the anti-friction bearingballs 18 and the said balls sustain the weight of the frame 18 andreduce the friction thereof.

As illustrated in Fig. 11 of the drawings, the runners 60 may beprovided with ground-wheels .60 which are adapted to travel over thesurface of the ground and perform the same functions as those describedhereinbefore for the runners 60. The blocks 35 are recessed at theirends and receive the vertically disposed rods 35 which in turn areattached at their ends to the disks 20 and 21 and which form guides forthe said blocks 35.

In Fig. 13 of the drawings a modification is illustrated which consistsof a flexible valve or fender 15 which is attached to the edge of thegrating 55, and which may be used in the place of the rotating brushes50, shown in Fig. 8 of the drawings. Each of the gratings is providedwith such a valve or fender 15 and they are adapted to substantiallycome together at their inner edges in inclined positions as illustratedin the said Fig. 13. The lower portions of the stalks of the plants maypass between the inner edges of the said fenders 4:5 as the material ofwhich they are composed is of sufllcient resiliency to move away fromthe stalks of the plant. lVhen, however, the said fenders 45 pass beyondthe stalks of the plant they will come together or substantially so andclose the passageway previously made for the stalks. Thus any cottonlint or bolls which should happen to fall upon the said fenders 45 willbe conducted to the endless belt conveyers 53.

By reference to Fig. 2 of the drawing it will be seen that the frictionpulleys 40 are arranged upon the shaft 23 and may slide longitudinallythereof and be secured in adjusted positions by means of set screws 40"which pass through the hubs of the said pulley wheels 10. Thus the saidwheels 40 whereby the rate of speed at which the said disk will rotatemay be regulated. Thus the shaft 12 and its attachments may be caused torotate at a rapid or slow speed, and thus provision is made for varyingthe speed at which the pickers will operate, the advantage gained beingthat all cotton would not probably require the same speed on the part ofthe pickers and the brush to remove the pods or bolls from the plants.
